To all whom it may concern lie it trnown that I, imnnns '1. vi li S1" in nu, n citizen ot the United Stntcs, residing at tilt. Louis, ldissouri, have invented a con loin new and. usetnl improvement in b xlll'iceLCzir-Zllrnclt Brnltcs, ol which tho lollowing: is :1 full, ctcnr, nnd exact description, such. is will cuuble other-rx skilled in the art to which it upper-talus to notice and usc the sonic, rcjt'in'encc heir hint to the nccoinpnnyins: drawings, i'forming part.- of this speciticntion, in .'hieli---- liigurc l is n side elevntionnl vi w ot' my iniprovod brnlic ringing; with ports of the brulco booms shown in section. Fig. 2 is it plain view of the in'nlto rigging.

lily invention relntes to new nnd useful innn'ovcnzcnts in b nlte rigging; for six wheel car trnclcs, the ,|i-ii:i :i'p:.ii object ot my in vention ilkli to provide :1 simple 'n'nd elliricnt brnlu'. nnmlinnisun hnving eon'rpnrntiicly few parts, :ind which mechanism is of tho i ls lnm' type.

further onion-t oi? .my invention is to provide it sit lc Lorin of six wheel brake. incelinnn-nu which; while capable ot being, )t-t wirious forms ot six wheel trucks, is particularly adopted For use in connection with wheel trucks hnving :t'rnmcs of the type shown in lhitont No. 1,068.599, issued July 521 .1013. I

With the :ibovennrl other objects in view, my invention consists in certain novel tentlircs of construction and arrangement of ports. hereinafter more fully described and (in imcd.

in the drawings 1 have illnstr-rtcd in dotted lines :1 six wheel truck having :1 one 'ccc ironic similar to the frame disclosed in tho potent above mentioned, and which i'rome- (:t'n'n'i'uises wiiecl pieces it) and trainsoins ill. Formed int'errzrt with or tixed to one, o'l the trntsonis :i brnclieti l2 and piv otzrllv connected thereto is one end or extremity of it broke lover l3). livotnlly connectcd to this lever at :1 suitable point hetwcen its (extremities the center lnulte beam lit, the shoes 't l ot which :ire ndnptcd to engage tho peripheries not the wheels on the cantor anlo of the truck. ormed on or lined to the otiicr transom is it lJtfittliQl 1 5 to which piiu'itslly connoctcil a brake lever to. 'llic pivot point ot this lever at n suitnblcpoint; bet-w its extremities and oivotnlly connected in our: of tilt cctremities of said lever is it broke boom 17. This beam isWinsido hung, that is, it is arranged so tlnit its shoes engnge tho inner portions of the peripheries of the corresponding); wheels. inside hung beam 18 is arranged so that its shoes engnge the inner portions of the wheels at the opposite end or the truck, and ,z-ivotnlly connected to a port of this brake benni, preferably the strut thereof, is :1 llonting: lever it). The pivot, point of this lever is at :1 point intermediate itsends, and pivot-ally connected to said lever, preferably at at point below the point of pivotal connlction with tho brnko beam 18, is one end of :i compression member, preferably :1 rod 2U. The opposite end of this compression member is pivotnlly connected to the lover l -l nt a point below the point of pivotal connection between said lever and the brake henna 1t.

The tension member 521 which is associated with the brnlce actuating mechanism carried by the car body is pivotnlly connected to an equalizing lever 22, nnd pivotally connected to this equalizing lover is one end of atension member 23, Preferably a rod, the opposite 0nd of which is pivobnlly connected to the lever l6. Oncend of 'a short tension ineznbor'ilt is pivotolly connected to the equalizing lever 22 and the 0p osite end of said tension member is pivotnlly connected to floating lever 19.

The operation of my improved brake will be readily understood from an inspection of the drawings wherein arrows indicate the direction of movement of the parts '20, 23, 2i and 21. When the latter is actuated to set the brakes. When rod 21 is actuated the levers 13, 16 and 19 will swing upon their fulcrulns, and simultaneously all the brake bruins will be moved so as to bring the brake shoes into engagement Withthc peripheries oi" the wheels.

A six whcetbrnke of my improved construction crnnposcd of but few parts, can be rendily assembled and combined with six wheel trucks, particularly those wherein one piece truck frames are utilized, and said brake pos 'esses superio advantages in point of simplicity, durability, and general cilicicncy.

It will be readily understood that minor changes in the sizc lform ondconstruction ot" the various parts of my improved brnlrc can be made and substituted for those herein 51mm]. and (impairing w the scope of for six whee-l trucks,n le /m? one f its extremities to :1 0911'- of Lynch, a brakebeam piv bad w said. mm at a point be- 155* it' iw a @wmnd lever 1551.11 001:. its extixunities to k 1 L10 truck, bra 1m bean! )1 "*Gi1fiiiy cormectsd 110 one 0f Una I=s'1'filnii'i%; if said set-11nd vein, 21
